Because the stability of work at present means it's not practical to do so. I could lose my job at any moment - and if I've bought a house, I'm stuck in the same city, looking for a limited amount of work. I rent at present, it's not ideal, but it means that I'm not tied to a certain geographic region - if I need to move, it's a hassle, but I don't have a house on a 25-year mortgage that I'm stuck trying to sell in a terrible market, I can just say to the landlord - right, I'm offski, here's the keys, bye.
